Title: Dry etching method
Inventor: TSUJIMOTO KAZUNORI
IPC: C23F4/00
Filed: 1983-08-10
Abstract: PURPOSE:To judge well the end of the etching of a material capable of forming a Y compound having a high vapor pressure when the material is etched with Y dissociated from gaseous XnYm, by monitoring the emission spectrum of Xl (each of X and Y is an atom or a molecule, and each of l, m and n is a positive integer). CONSTITUTION:For example, when W is etched with SF6, the end of the etching is judged from a change in the intensity of the emission spectrum of S2. It is possible to consider that numbers of dissociated molecules such as F, SFn(n= 0-6) and S2 or molecules produced by the recombination of such dissociated molecules are present in plasma by the etching reaction. When emission spectra during the etching of W are examined, it is apparent that the emission spectrum of S2 appears intensely. The emission spectrum of S2 also appears when W is not present in SF6 plasma, yet the intensity is considerably lower than that of the emission spectrum of S2 during the etching of W. Accordingly, the end of the etching of W can be judged in a high S/N ratio.

Filed: 1999-05-26
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of stringy or granular artifacts and noises in generating a luminance signal of high frequency from an image signal obtained from an image pickup device such as a single CCD. SOLUTION: In the signal generation method, a luminance signal YL of low frequency on each pixel position is generated from an image pickup signal so obtained by a single CCD 1, the flatness degrees H1 to H4 of signal values in the vertical, horizontal and oblique directions of each pixel position are calculated from the signal YL and the direction of the smallest flatness degree is found out. A high frequency luminance signal generation means 4 finds out the luminance value of each pixel position by interpolating operation by using the signal values of pixel positions adjacent to the pixel position concerned in the direction where the flatness degree of the signal value in each pixel position is the smallest.  All R, G and B chrominance signals are used for the operation, but when there is no corresponding chrominance signal, a chrominance signal of low frequency calculated for finding out the low frequency luminance signal YL is used. The found luminance value is generated as a high frequency luminance signal YH.
